3 Claims. (Cl. 4-28') This invention relates to a waste-pipe fitting form an internal shoulder 13. The top of the and more particularly to such a itting especially body is formed with an outwardly-extending, bevadapted for use in connection with sinks, disheled clamping-ilangc 14. washer tanks, and the like.

It will be evident that the embodiment of the invention herein disclosed is merely illustrative and may be modified or departed from in many ways without departing from the spirit and scope of the invention as pointed out in and limited only by the appended claims.

I claim:

1. A waste-pipe. fitting comprising: a hollow body with upper and lower open ends; a strainer basket removably seated in the upper part of the body; a plug-supporting lug in the lower part of the body and extending toward the upright center axis of the body, said lug being substantially free from any enlargement or the like adjacent said center axis; a closure seat above the lug; a closure plug having a closure portion adapted to i'lt said closure seat and having a support below said closure portion, said support being adapted to extend below the supporting surface of said lug when said closure portion is in engagement with said closure seat and being adapted to rest upon said lug to hold said closure portion spaced above said closure seat; and a handle-'member attached to the closure plug and extending `up through the basket and being slidable and rotatable relatively to the basket to actuate said closure plug to closed and open positions without moving the basket.

2. A waste-pipe fitting comprising: a hollow body with upper and lower open ends; a strainer basket removably seated in the upper part of the body; a plug-supporting lug in the lower part of the body and extending substantially horizontally toward the upright center axis of the body; a

closure seat above the lug; a disk-shaped closure plug having a closure portion adapted to t said closure seat and having a support below and closely against the under surface of said closure portion with no space between the end of said support and the under surface of said closure portion at such outer end or ends of the said support remote from said center axis, said support being adapted to extend below the supporting surface of said lug when said closure portion is in engagement with said closure seat and being adapted to rest upon said lug to hold said closure portion spaced above said closure seat; and a handle-member attached to the closure plug and extending up through the basket and being slidable and rotatable relatively to the basket to actuate said closure plug to closed and open positions without moving the basket.

3. A waste-pipe fitting comprsing a hollowbody with upper and lower open ends; a strainer basket removably seated in the upper part of the body; a plurality of circumferentially-spaced plug-supporting lugs in the lower part of the body and extending toward the upright center axis of the body, said lugs being substantially free from any enlargement or the like or connection with each other adjacent said center axis; a closure seat above the lugs; a closure plug having a disk-shaped closure portion adapted to t said closure seat and havinga support below and closely against the under surface of said closure portion with no space between the end of said support and the under surface of said closure portion at such outer end or ends of the said support remote from said center axis, said support being adapted to extend below the supporting surface of said lugs when said closure portion is in engagement with said closure seat and being adapted to rest upon one or more of said lugs to hold said closure portion spaced above said closure seat; and a handle-member attached to the closure plug and extending up through the basket and being slidable and rotatable relatively to the basket to actuate said closure plug to closed and open positions without moving the basket.
